Find Your Bra & Underwire Size
*This Size Guide and Emerald Erin Patterns use UK Bra Sizing
1. Find Your Band Size
Measure directly under your bust, holding the tape measure snug. If using cm, convert the measurement to inches. Round this number to the closest even number, rounding up if you are directly in between. This is your band size.
2. Find Your Cup Size
Measure over the fullest point of your bust, be sure not to pull the tape measure tight. If using cm, convert the measurement to inches. Subtract your band size, from your full bust measurement. Each inch of difference equals 1 cup size.
E.G. 40(full bust measurement) - 36(band size) = 4 (D cup)
3. Find Your Bra Size
Put your band size and cup size together to get your bra size.
E.G. 36D
4. Find Your Underwire Size
If your bra style includes an underwire, consult this wire chart to find the standard size of wire for your bra size.
